This project will help Corix Water Systems to improve their dissolved air flotation (DAF) water treatment process. A computational fluid dynamics (CFD) model of a DAF system has been developed by the research team, but needs validation. Corix is building a pilot-scale DAF system to test methods to improve performance. Through this NSERC CRD project, an expanded pilot-scale testing program will be conducted to generate data specifically needed to validate the CFD modeling results. With a validated CFD model, Corix and the University team will then be able to explore a much wider range of DAF system configurations than would be otherwise possible, including changes to the DAF separation zone dimensions, air fraction, and position of the collection system, with the goal of improving the maximum loading rate from the current 10 m/hr to a loading rate in the order of 30-40 m/hr, which is required to compete with leading international DAF vendors.

该项目将帮助Corix Water Systems改进其溶气气浮（DAF）水处理工艺。研究小组已经开发了一个计算流体动力学（CFD）模型，但需要验证。Corix公司正在建立一个试验规模的数据处理系统，以测试提高性能的方法。通过这个NSERC CRD项目，将进行扩大的中试规模测试计划，以生成验证CFD建模结果所需的数据。利用经过验证的CFD模型，Corix和大学团队将能够探索比其他方式更广泛的反渗透系统配置，包括反渗透分离区尺寸，空气分数和收集系统位置的变化，目标是将最大装载速率从目前的10米/小时提高到30-40米/小时的装载速率，这是与领先的国际销售商竞争所必需的。
